Description
Oppfinnelsen vedrører vaskepulver med regulert skumming som inneholder alkylbenzensulfonat som vaskeaktiv komponent, primært beregnet på bruk i vaskemaskiner med front-ilegg eller av trommeltype. The invention relates to washing powder with regulated foaming that contains alkylbenzene sulphonate as a washing active component, primarily intended for use in front-loading or drum-type washing machines.
De fleste vaskepulvere med regulert skum inneholder anioniske overflateaktive midler vanligvis i blanding med ikke-ionisk overflateaktive midler, og skum som utvikles av Most detergents with regulated foam contain anionic surfactants usually mixed with nonionic surfactants, and foam developed by
de overflateaktive midler reguleres ved hjelp av et skumundertrykkende middel, idet såpe er det middel som det er mest van-lig å anvende. Imidlertid begynner produsentene å være villi-ge til å akseptere de økede omkostninger som er forbundet med å anvende andre skumregulerende midler enn såpe på grunn av den økede fleksibilitet disse gir i sammensetning av den vaskeaktive komponent. Allikevel er det nødvendig å redusere til et minimum de ytterligere omkostninger som bruk av disse forbindelser betyr. the surface-active agents are regulated by means of a foam-suppressing agent, soap being the most commonly used agent. However, manufacturers are beginning to be willing to accept the increased costs associated with using foam control agents other than soap due to the increased flexibility these provide in the composition of the detergent active component. Even so, it is necessary to reduce to a minimum the additional costs that the use of these compounds means.
Vi har nå oppdaget at når et alkylbenzensulfonat anvendes som den anioniske overflateaktive komponent i vaskepulveret, og en alkylfosforsyre eller et salt derav anvendes som det skumregulerende middel, så kan det oppnås meget effektiv skum-regulering ved en utvelgelse av den type alkylbenzensulfonat som anvendes. We have now discovered that when an alkylbenzenesulfonate is used as the anionic surfactant component in the washing powder, and an alkylphosphoric acid or a salt thereof is used as the foam control agent, very effective foam control can be achieved by selecting the type of alkylbenzenesulfonate used.
Følgelig tilveiebringer oppfinnelsen et vaskepulver som omfatter 5 % eller mer i vekt av vannløselige salter av alkyl-benzensulf onater hvor det totale innhold av alkylgrupper som inneholder 14 eller flere karbonatomer er mindre enn 15 vekt% regnet på alkylmaterialet, og et skumregulerende middel omfattende en alkylfosforsyre eller et salt derav. Accordingly, the invention provides a washing powder comprising 5% or more by weight of water-soluble salts of alkyl benzene sulfonates where the total content of alkyl groups containing 14 or more carbon atoms is less than 15% by weight calculated on the alkyl material, and a foam control agent comprising an alkyl phosphoric acid or a salt thereof.
Alkylbenzenforløperne til sulfonatene i henhold til oppfinnelsen kan fremstilles av krakket-voks-olefiner, av polymeriserte lav-olefiner eller ved enhver annen ønsket måte, forutsatt at de tilsvarer den kjedelengde og de molekylvekt-kriterier som oppfinnelsen fastsetter. The alkylbenzene precursors to the sulfonates according to the invention can be prepared from cracked-wax olefins, from polymerized low-olefins or by any other desired method, provided that they correspond to the chain length and the molecular weight criteria that the invention establishes.
Karakteristikaene for alkylbenzensulfonatene er uvanlig betydningsfulle for oppfinnelsen, da vi har oppdaget at hvis sulfonater som inneholder store andeler av alkylgrupper med 14 eller flere karbonatomer anvendes, krever det skum som pro-duseres signifikant større mengder av anvendt skumregulerende middel for at man skal oppnå den skumprofil man setter seg som mål. The characteristics of the alkylbenzene sulfonates are unusually significant for the invention, as we have discovered that if sulfonates containing large proportions of alkyl groups with 14 or more carbon atoms are used, the foam that is produced requires significantly larger amounts of the foam control agent used in order to achieve the foam profile you set yourself as a goal.
Det foretrekkes at det totale innhold av alkylsulfonater som har 14 eller flere karbonatomer er mindre enn 5 vekt%. It is preferred that the total content of alkylsulfonates having 14 or more carbon atoms is less than 5% by weight.
Det foretrekkes også at middelmolekylvekten til det usulfo-nerte hydrokarbon er fra 235 til 245. It is also preferred that the average molecular weight of the unsulfonated hydrocarbon is from 235 to 245.
Alkylbenzensulfonatene kan anvendes i kombinasjon med andre anioniske vaskeaktive substanser. Eksempler på slike materialer er natrium-primær- og -sekundær-alkylsulf ater, natrium-olefinsulfonater og natrium-alkansulfonater. Av disse foretrekkes de C^2~C2o~Primære°9-sekundære alkylsulfater. The alkylbenzene sulphonates can be used in combination with other anionic detergent-active substances. Examples of such materials are sodium primary and secondary alkyl sulphates, sodium olefin sulphonates and sodium alkanes sulphonates. Of these, the C^2~C2o~Primary°9-secondary alkyl sulfates are preferred.
Foretrukne totale mengder av anionisk overflateaktivt middel i produktene i henhold til oppfinnelsen er fra 5 til 25 vekt%, helst 5-15 vekt%. Det er ønskelig at de utvalgte alkylbenzensulfonater vil utgjøre minst halvparten av disse mengder og i alle fall minst 5 vekt% av blandingen. Preferred total amounts of anionic surfactant in the products according to the invention are from 5 to 25% by weight, preferably 5-15% by weight. It is desirable that the selected alkylbenzene sulphonates will make up at least half of these quantities and in any case at least 5% by weight of the mixture.
Ikke-ioniske overflateaktive midler kan også være til stede i produktene i henhold til oppfinnelsen i mengder på opp til 15 vekt%. Foretrukne ikke-ioniske overflateaktive midler er de Cg-C^^-primære og -sekundære alifatiske alkoholer, etoksylert med 3-25 mol etylenoksyd pr. mol alkohol. Spesielt foretrekkes de C,~-C. D-prim.-alkoholetoksylater som inneholder Non-ionic surfactants can also be present in the products according to the invention in amounts of up to 15% by weight. Preferred nonionic surfactants are the Cg-C^^-primary and -secondary aliphatic alcohols, ethoxylated with 3-25 mol of ethylene oxide per moles of alcohol. Particularly preferred are those C,~-C. D-prim.-alcohol ethoxylates containing
IO loIO laughed
5-15 mol etylenoksyd. Vi har funnet C^_^-^ >ri. m.. -alkohol 7E0-etoksylat å være best ut fra et vaskeevnesynspunkt. 5-15 moles of ethylene oxide. We have found C^_^-^ >ri. m.. -alcohol 7E0-ethoxylate to be best from a detergency point of view.
Den annen essensielle komponent i produktene i henhold til oppfinnelsen er en alkylfosforsyre, eller et salt derav, fortrinnsvis blandet med en hydrokarbonolje eller -voks. De foretrukne alkylfosforsyrer har den generelle formel The other essential component in the products according to the invention is an alkyl phosphoric acid, or a salt thereof, preferably mixed with a hydrocarbon oil or wax. The preferred alkyl phosphoric acids have the general formula
hvor A er -0H eller R~0(EO) -, R, og R_ er like eller forskjel-2 m 1 ^ 2 J lige C^2_<C>24'f°rtrinnsv:i-s ci6~<C>22'rettkje<3et eller forgrenet, mettet eller umettet alkyl, i alt vesentlig C^g-C^g-lineær-mettede grupper, og m og n er like eller forskjellige og er 0 eller et helt tall fra 1 til 6. Fortrinnsvis er A lik -0H og n er 0, slik at forbindelsene er monoalkylfosforsyrer, fortrinnsvis med lineære alkylgrupper. Disse forbindelser kan være til stede enten som den frie syre eller som et natrium-, kalium-, kalsium- eller magnesiumsalt eller en blanding derav. where A is -0H or R~0(EO) -, R, and R_ are the same or different-2 m 1 ^ 2 J equal C^2_<C>24'f°rtrinnsv:i-s ci6~<C>22' straight-chain or branched, saturated or unsaturated alkyl, substantially C^g-C^g-linear-saturated groups, and m and n are the same or different and are 0 or an integer from 1 to 6. Preferably, A is equal to - 0H and n are 0, so that the compounds are monoalkyl phosphoric acids, preferably with linear alkyl groups. These compounds may be present either as the free acid or as a sodium, potassium, calcium or magnesium salt or a mixture thereof.
Mengden av alkylfosforsyren eller saltet derav som anvendes i vaskemiddelblandingene kan varieres innen vide grenser fra et minimumsnivå på ca. 0,05 % og opp til et praktisk maksimum på ca. 5, fortrinnsvis ca. 0,1 til ca. 3 % i vekt. Høy-ere nivåer enn 5 % kan anvendes, men dette ville være uøkono-misk og ville vanligvis ikke gi noen produktfordeler. The amount of the alkyl phosphoric acid or its salt used in the detergent compositions can be varied within wide limits from a minimum level of approx. 0.05% and up to a practical maximum of approx. 5, preferably approx. 0.1 to approx. 3% by weight. Higher levels than 5% can be used, but this would be uneconomical and would usually not provide any product benefits.
Egnede hydrokarbonvokser for anvendelse i vaskemiddelblandingene er vann-uløselige materialer av enten syntetisk, Suitable hydrocarbon waxes for use in the detergent compositions are water-insoluble materials of either synthetic,
mineralsk, vegetabilsk eller animalsk opprinnelse, som er dis-pergarbare i vaskemiddelløsningene. Voksene bør normalt smel-te ved en temperatur mellom ca.20°C og ca. 120°C, fortrinnsvis ikke over ca. 90°C og spesielt i området fra ca. 30°C til ca. 70°C, dvs. lavere enn det maksimum som er tenkt for vasketem-peraturer for vaskemiddelblandingene. mineral, vegetable or animal origin, which are dispersible in the detergent solutions. The waxes should normally melt at a temperature between approx. 20°C and approx. 120°C, preferably not above approx. 90°C and especially in the area from approx. 30°C to approx. 70°C, i.e. lower than the maximum intended for washing temperatures for the detergent mixtures.
De foretrukne vokser er av mineralsk opprinnelse, spesielt slike som stammer fra petroleum, inklusive mikrokrysta.l-linske og oksyderte mikrokrystallinske petroleumvokser, petroleumgelé ("Vaseline") og paraffinvokser. Petroleumgelé er korrekt en halvfast voks, vanligvis med et dråpesmeltepunkt på ca. 50°C, men er for ettvinthets skyld her gruppert sammen med andre faste vokser. Syntetiske vokser som f.eks. Fischer-Tropsch- og oksyderte Fischer-Tropsch-vokser, eller montanvok-ser, eller naturlige vokser slik som bivoks, candelilla- og carnauba-voks, kan anvendes om så ønskes. Hvilke som helst av de vokser som er beskrevet kan anvendes alene eller i blanding med andre vokser. Voksene må være lett dispergerbare i vaskebadet, men ikke løselige i det, og de bør fortrinnsvis ikke ha svært høye forsåpningstall f.eks. ikke over ca. 100. Emulgerings- eller stabiliseringsmidler for voksene kan også inkluderes i vaskemiddelblandingen. The preferred waxes are of mineral origin, especially those derived from petroleum, including microcrystalline and oxidized microcrystalline petroleum waxes, petroleum jelly ("Vaseline") and paraffin waxes. Petroleum jelly is correctly a semi-solid wax, usually with a droplet melting point of approx. 50°C, but for the sake of consistency are grouped here together with other solid waxes. Synthetic waxes such as Fischer-Tropsch and oxidized Fischer-Tropsch waxes, or montan waxes, or natural waxes such as beeswax, candelilla and carnauba wax, can be used if desired. Any of the waxes described may be used alone or in combination with other waxes. The waxes must be easily dispersible in the washing bath, but not soluble in it, and they should preferably not have very high saponification figures, e.g. not over approx. 100. Emulsifiers or stabilizers for the waxes can also be included in the detergent mixture.
Mengden av voks er normalt fra ca. 0,05 til :ca. 10%, fortrinnsvis ca. 0,1 til ca. 5 % og spesielt ca. 0,5 til ca. 3 % i blandingen . Den totale mengde av alkylfosforsyren eller saltet og hydrokarbonvoksen er generelt fra ca. 0,2 til ca. 20 % i vekt av blandingen, fortrinnsvis ca. 0,5 til ca. 5 vekt%. Forholdet mellom mengden av alkylfosforsyren eller saltet og voksen kan varieres innen vide grenser fra ca. 1:25 til ca. 10:1 vektdeler, men er generelt fra ca. 1:20 til ca. 10:1 vektdeler, fortrinnsvis fra ca. 1:10 til ca. 1:1 vektdeler. The amount of wax is normally from approx. 0.05 to :approx. 10%, preferably approx. 0.1 to approx. 5% and especially approx. 0.5 to approx. 3% in the mixture. The total amount of the alkyl phosphoric acid or salt and the hydrocarbon wax is generally from about 0.2 to approx. 20% by weight of the mixture, preferably approx. 0.5 to approx. 5% by weight. The ratio between the amount of the alkylphosphoric acid or the salt and the wax can be varied within wide limits from approx. 1:25 to approx. 10:1 parts by weight, but are generally from approx. 1:20 to approx. 10:1 parts by weight, preferably from approx. 1:10 to approx. 1:1 parts by weight.
I tillegg til voksen som kan anvendes sammen med alkylfosforsyren eller saltet i vaskemiddelblandingen, kan en hydrokarbonolje også være til stede, enten tilsatt separat eller sammen med voksen, f.eks. i den hensikt å lette tilset-ning av voksen eller å modifisere dens smeltepunkt eller dis-pergeringskarakteristika. In addition to the wax which may be used with the alkyl phosphoric acid or salt in the detergent mixture, a hydrocarbon oil may also be present, either added separately or together with the wax, e.g. in order to facilitate the addition of the wax or to modify its melting point or dispersion characteristics.
Eksempler på egnede flytende hydrokarboner er mineralske, vegetabilske eller animalske oljer hvorav farveløse mineralol-jer foretrekkes. Enten lett eller tung mineralolje eller blandinger derav kan anvendes, men naturligvis må ethvert flytende hydrokarbon som anvendes ha lav flyktighet ved normale tøy-vasketemperaturer. Andre oljer som kunne anvendes om så ønskes, er vegetabilske oljer, f.eks. sesamolje, bomullsfrøolje, maisolje, søt mandelolje, olivenolje, hvetekimolje, riskliolje eller jordnøttolje, eller slike animalske oljer som lanolin, okseklovefett, benolje, spermolje eller torskeleverolje. Hvilke som helst slike oljer som anvendes, bør naturligvis ikke være sterkt farvet, ha sterk lukt eller på annen måte være uakseptable for bruk i en vaske middelblanding. Examples of suitable liquid hydrocarbons are mineral, vegetable or animal oils, of which colorless mineral oils are preferred. Either light or heavy mineral oil or mixtures thereof can be used, but of course any liquid hydrocarbon used must have low volatility at normal laundry temperatures. Other oils that could be used if desired are vegetable oils, e.g. sesame oil, cottonseed oil, corn oil, sweet almond oil, olive oil, wheat germ oil, rice bran oil or peanut oil, or such animal oils as lanolin, ox hoof fat, bone oil, sperm oil or cod liver oil. Any such oils that are used should, of course, not be strongly colored, have a strong odor or otherwise be unacceptable for use in a detergent mixture.
Andre skumregulerende midler kan også anvendes i kombinasjon med dé alkylfosforsyrebaserte skumregulerende midler. Eksempler på disse er silikonbaserte reguleringsmidler, f.eks. partikler av granulert natriumtripolyfosfat impregnert med organopolysiloksan og innkapslet i voks, eller hydrofobe sili-siumdioksydpartikler impregnert med et organopolysiloksan. Other foam control agents can also be used in combination with the alkyl phosphoric acid-based foam control agents. Examples of these are silicone-based regulators, e.g. particles of granulated sodium tripolyphosphate impregnated with organopolysiloxane and encapsulated in wax, or hydrophobic silicon dioxide particles impregnated with an organopolysiloxane.
Et annet eksempel, som er av spesiell interesse, er en partik-kel som har en sfærisk eller sylindrisk kjerne, gjerne av sukrose, belagt med et absorpsjonsmiddel, f.eks. titandioksyd,. som er impregnert med polysiloksan, idet hele partiklen er belagt med voks. Blandinger av polysiloksaner og vokser eller etylendistearimider, enten alene eller i blanding med vokser, kan også anvendes som hjelpe-skumregulerende midler. Another example, which is of particular interest, is a particle which has a spherical or cylindrical core, preferably of sucrose, coated with an absorbent, e.g. titanium dioxide,. which is impregnated with polysiloxane, the entire particle being coated with wax. Mixtures of polysiloxanes and waxes or ethylene distearimides, either alone or in a mixture with waxes, can also be used as auxiliary foam control agents.
En vaskeevnebygger vil normalt bli inkludert i produktene i henhold til oppfinnelsen. Flere egnede vaskeevnebyggere er velkjente og kommersielt tilgjengelige, og eksempler på slike er alkalimetall-, orto-, pyro- og tripolyfosfater, alkalimetallkarbonater og -bikarbonater, alkalimetallpolyfos-fonater, alkalimetallnitriltriacetater og den hærskare av organiske byggere som er foreslått som respons på antifosfat- holdningen, og eksempler på disse er natriumkarboksymetyloksy-suksinat, natriumcitrat og natriumpolyakrylat. A detergent builder will normally be included in the products according to the invention. Several suitable detergency builders are well known and commercially available, examples of which are alkali metal, ortho, pyro and tripolyphosphates, alkali metal carbonates and bicarbonates, alkali metal polyphosphonates, alkali metal nitrile triacetates and the host of organic builders that have been proposed in response to the anti-phosphate attitude , and examples of these are sodium carboxymethyloxysuccinate, sodium citrate and sodium polyacrylate.
Andre vaskeevnebyggere er kombinasjonen natriumkarbonat/ findelt kalsitt og de krystallinske eller amorfe aluminosili-kalt-kationbyttematerialer. Disse byggere kan anvendes i en mengde av fra 5 til 80 vekt% regnet på blandingen, fortrinnsvis 10-60 vekt%. Other detergency builders are the combination of sodium carbonate/ finely divided calcite and the crystalline or amorphous aluminosilicate cation exchange materials. These builders can be used in an amount of from 5 to 80% by weight based on the mixture, preferably 10-60% by weight.
Produktene i henhold til oppfinnelsen kan også inneholde oksygenblekemidler, f.eks. natriumperborat og natriumperkar-bonat, fyllstoffer som f.eks. natriumsulfat, og fuktighet og mindre komponenter som f.eks. oppslemmingshydrotroper, korro-sjonsinhibitorer, smussbærende midler, antiaskedannende midler, antioksydanter, fluorescerende midler og optiske hvitemidler, enzymer, blå-hvitemidler og pigmenter og farvestoffer. The products according to the invention may also contain oxygen bleaching agents, e.g. sodium perborate and sodium percarbonate, fillers such as sodium sulphate, and moisture and minor components such as e.g. slurry hydrotropes, corrosion inhibitors, dirt carriers, anti-ash forming agents, antioxidants, fluorescent agents and optical brighteners, enzymes, blue-whiteners and pigments and dyes.
Oppfinnelsen skal i det følgende illustreres ved hjelp av eksempler. In what follows, the invention will be illustrated by means of examples.
Eksempel 1Example 1
Det ble fremstilt en rekke forstøvningstørkede pulvereA number of spray-dried powders were produced
i henhold til følgende generelle resept og ved den følgende generelle metode: according to the following general prescription and by the following general method:
Et skumundertrykkende middel i form av en blanding av A foam suppressant in the form of a mixture of
1 del av C-^g-alkylfosforsyreester med 3 deler petroleumgelé ble sprøytet på dette pulver mens det falt i en kaskade fra det ene transportbelte til et annet. 24 deler natriumperborat-tetrahydrat ble så blandet med det forstøvningstørkede pulver, sammen med parfyme. 1 part of C-4-alkyl phosphoric acid ester with 3 parts of petroleum jelly was sprayed on this powder as it fell in a cascade from one conveyor belt to another. 24 parts sodium perborate tetrahydrate was then mixed with the spray dried powder, along with perfume.
De skum som ble produsert av hvert pulver, som varierte fra det ene til det annet som vist nedenunder, ble fastsatt på følgende måte: 2,5 kg ladninger med hvitt bomullsfrottéhåndklestoff ble vasket i automatiske vaskemaskiner med front-ilegg av merket Hoover (registrert varemerke) med vann av 26°H hårdhet og med 200 g pulver. Det vaskeprogram som ble brukt, vasker ved 90°C. The lathers produced by each powder, which varied from one to the other as shown below, were determined as follows: 2.5 kg loads of white cotton terry toweling fabric were washed in front-load automatic washing machines of the brand Hoover (registered trademark ) with water of 26°H hardness and with 200 g of powder. The washing program used washes at 90°C.
Skumhøyden for hvert vaskebad ble målt ved hjelp av en vilkårlig skala festet til vinduet i maskinene. Hver skum-fastsettelse ble utført fire ganger, idet den gjennomsnittlige skumhøyde er angitt i de følgende tabeller, som er interpo-lasjoner fra en kurve. Kurven ble oppstilt direkte fra resultatene i forsøkene. The foam height for each wash bath was measured using an arbitrary scale attached to the window of the machines. Each foam determination was carried out four times, the average foam height being given in the following tables, which are interpolations from a curve. The curve was drawn up directly from the results of the experiments.
I den føste serie med forsøk ble det anvendt 3 sett pulver, sett A var kontrollsettet og inneholdt et sulfonat av et alkylbenzen med molekylvekt 255, og sett B og C, dvs. settene i henhold til oppfinnelsen, inneholdt et sulfonat av et alkylbenzen ed molekylvekt henholdsvis 241 og 242. Den aktuelle alkylkjedefordeling er vist i tabell 1. In the first series of experiments, 3 sets of powders were used, set A was the control set and contained a sulfonate of an alkylbenzene with a molecular weight of 255, and sets B and C, i.e. the sets according to the invention, contained a sulfonate of an alkylbenzene with a molecular weight of 241 and 242 respectively. The relevant alkyl chain distribution is shown in table 1.
Fem varianter av hvert pulversett ble fremstilt ved å sprøyte pulveret med henholdsvis 0,6, 0,8, 1,0, 1,2 og 1,4 vekt% av alkylfosforsyre/petroleumgeléblandingen, og skumhøy-den ble målt som beskrevet. Resultatene er vist i tabell 2. Five variants of each powder set were prepared by spraying the powder with respectively 0.6, 0.8, 1.0, 1.2 and 1.4% by weight of the alkyl phosphoric acid/petroleum jelly mixture, and the foam height was measured as described. The results are shown in table 2.
Det kan sees at mens pulver A som inneholdt et alkyl-benzensulf onat med vesentlige andeler av C^-, 0<3 ^ ±s~ alkylgrupper i blandingen produserer overskumming ved de lavere innhold av skumundertrykkende middel, gjør pulverne i overensstemmelse med oppfinnelsen ikke det, og de produserer faktisk bare spor av skum ved de større innhold av skumundertrykkende middel. It can be seen that while powder A which contained an alkyl-benzene sulfonate with substantial proportions of C^-, 0<3 ^ ±s~ alkyl groups in the mixture produces overfoaming at the lower contents of foam suppressant, the powders in accordance with the invention do not , and they actually only produce traces of foam at the higher contents of foam suppressant.
